A particular collection of source (or withnesses) present information to the author (or lawyers) and the author comes to some understanding. Then the author explains how she or he came to that conclusion and points to or presents the bits of evidence that made it possible. Consider what information is not included. Was the trial fair even though a key witness was not called to testify? Has your author only let those facts that support the thesis testify in the article? How might you find out?
